About
Slinger was created to help tackle climate change by making event transportation more sustainable. By encouraging visitors to share rides, we reduce CO₂ emissions and make attending events a more social and enjoyable experience.
Yes, absolutely. Transport accounts for 60-85% of CO₂ emissions from events. Sharing rides significantly reduces this impact, benefiting both the climate and event sustainability.
Our mission is to cut down CO₂ emissions from transportation to events. Since transport is the main polluter for events, we aim to provide a simple, effective way for visitors to share rides. This benefits the environment, saves money, and builds visitor engagement.
Slinger is currently active across Europe and the United Kingdom, with ambitions for global expansion to support sustainable event mobility worldwide.
Our headquarters are located in Amsterdam, Netherlands, at Overtoom 323. Our core team works from this office, while other team members work remotely. Together, we are a flexible and dedicated team committed to creating sustainable impact in the events industry.
Benefits
Together, we tackle the largest source of your event’s emissions: visitor transport. Slinger reduces your visitors’ CO₂ footprint by making ride-sharing an integral part of the event experience.
Slinger’s ride-sharing isn’t just about sharing a car; it’s about shared interests. Your visitors often have a passion for the same event. By riding together, they reduce their footprint and share costs.
Slinger is a widget that seamlessly integrates with existing websites and apps. We focus on the destination and enhancing the visitor experience, offering a smooth, personalized journey.

Widget
On this page you’ll see an example of the Slinger widget. By adding two lines of code to your website or app, your own widget appears, allowing visitors to arrange rides to your event.
No, only the events you add in your dashboard are visible in your widget, meaning only visitors to your event can arrange rides with each other.
In your website or app’s widget, drivers can easily list available seats. Passengers can then book a ride, and both parties receive an email confirmation. This ensures a simple and safe way to share rides.
Yes, visitors can fully control their rides through their personal account page, where they can adjust times, dates, or cancel rides if necessary. Any passengers will be automatically informed of changes.
Yes, if no rides are available, passengers can join a waiting list. As soon as a new ride becomes available, they will be notified and can book immediately.
Yes, drivers can leave a message for passengers after listing a ride, providing details like the meeting point, estimated departure time, or other practical info to make the trip smooth.
Yes, drivers can choose to offer only an outbound ride, only a return ride, or a round trip, based on their schedule and availability. This flexibility makes ride-sharing accessible to everyone.
Yes, visitors can share the expenses, which adds an extra incentive for offering rides. Drivers can set a fee that passengers pay directly at booking via our payment provider, Stripe, making cost-sharing simple and transparent.
Drivers are paid 24 hours after a successful ride, ensuring fast and reliable payment, making ride-sharing more attractive to drivers.
The widget is available in various languages, including Dutch, English, German, French, Danish, Hungarian, Spanish, Slovak, Italian, and Czech. If a specific language isn’t yet supported, we can add it within 48 hours.
Dashboard
The Slinger dashboard is designed for organizations to easily manage and monitor their ride-sharing initiatives. In the dashboard, you can:
Create and manage widgets and events: Customize widgets for each event, adjusting settings to optimize user experience.
View real-time reports: Track impact, including kilometers saved, CO₂ reductions, and user activity at both event and organization levels.
Analyze user data and engagement: See how often the widget is used and identify user engagement patterns to make further optimizations.
Yes, you can create multiple widgets for different events or locations. Each widget has its own price, and our team can help you determine the most efficient widget strategy for your organization.
Yes, you can manage multiple events within a single widget, making it easy to use one widget for an ongoing event program.
We base calculations on the distance between departure and destination locations of participants, assuming riders would otherwise drive individually to the event. A 20% adjustment factor accounts for cases where participants would not travel alone. For CO₂ calculations, we use the average emissions of a passenger vehicle, based on the latest statistics and environmental standards.
The media hub provides royalty-free promotional materials, such as visuals and banners, designed to promote ride-sharing. Use these materials on your website, in newsletters, and on social media.
The dashboard reports the following data to help you measure the widget’s impact:
Number of rides: Unique rides organized via the widget.
Kilometers saved: Total kilometers saved through shared rides.
CO₂ reduction: Estimated CO₂ emissions reduction due to shared rides.
User engagement: Insights into widget usage, such as ride offers, ride requests, and the percentage of users who share rides.
These reports help you track the effectiveness of your ride-sharing initiative and show your organization’s contribution to sustainability.

Data security
Our servers are located in Amsterdam, hosted by DigitalOcean, which complies with strict international and local data protection standards.
Yes, clients can view and manage their stored data through the user dashboard, with options to edit, download, or delete organization-specific data.
We retain data as long as your account is active. After account termination, we hold data for an additional period—typically between 6 months to 2 years, depending on data type and legal requirements. This allows us to meet administrative needs and handle any inquiries or disputes effectively. After this period, all data is securely deleted from our systems.
We are fully GDPR-compliant. Measures include appointing a Data Protection Officer, implementing privacy-by-design, and providing clear options for users to exercise their privacy rights.
The right to be forgotten allows you to request the deletion of your personal data from our systems when it is no longer needed for its original purpose or if you withdraw consent without another legal basis for processing. To exercise this right, submit a request to privacy@slinger.to. We will delete your data unless there is a legal obligation or legitimate interest to retain it, notifying you of the request’s outcome within 30 days.
In the unlikely event of a data breach, we follow a strict protocol that includes notifying relevant authorities and affected parties within 72 hours. We also take immediate corrective actions to address the breach’s cause.
Safety
Slinger provides various options for user safety. Users have control over their own safety by choosing who they ride with and what information they share. We also offer practical safety tips, such as informing someone of your ride details and sharing your location when possible, to help users make informed choices and ride with peace of mind.
Yes, users are typically covered by the standard insurance applicable to car trips. In most cases, the driver’s liability insurance covers damages to third parties. We advise drivers and passengers to check their own insurance policies in advance and discuss any questions. Slinger does not impose specific insurance requirements but encourages users to ensure their coverage applies.
No, the organization is not liable for incidents during rides. Users agree to our terms upon registration, which clarify that they are responsible for their own participation. We provide all users with clear guidelines and best practices to promote a safe and enjoyable ride experience. Any disputes or claims are handled between the parties involved, potentially using their own insurance or legal steps as needed.
Yes, after a ride, passengers can rate their driver, and vice versa. Ratings help maintain platform quality and build community trust. Users can share their experiences through our dashboard, rating drivers on points such as safety and reliability.
If an incident occurs, we recommend contacting the relevant insurance providers immediately. Legal or medical assistance may also be useful if needed. Slinger provides guidelines for reporting incidents within the platform to help us take appropriate action and support the involved parties.
Slinger values platform reliability. All users must register with their email and phone number, which we verify to create a safe and reliable environment. Users can also add details like car type and license plate on their profile, offering more transparency and enhancing the experience for all users.
Yes, users can currently contact their ride partner via phone and email to coordinate details like pickup location and time or ask questions. We are working on an internal messaging system to allow users to communicate directly within the platform, making it easier to stay in touch while keeping data secure.
Rather than strict rules, we rely on mutual agreements between users. We encourage open communication to set expectations ahead of time, whether it’s about smoking, music preferences, or other personal preferences. We believe riders can collaboratively agree on what is comfortable and safe for them. Our terms of service provide guidelines, but the details are up to the users to shape their travel experience.
If you experience any issues, you can report them through Slinger's dashboard. We take complaints seriously and will work to resolve the situation. Users can provide feedback and address any problems to help us continually improve the platform and ensure a safe experience for everyone.
